. I REINFORCED CONCRETE CONSTRUCTION.

Specification of Letters Patent.

Application filed August 31, 1912. Serial No. 717,997.REIS

To all whom it may concern:

Be it known that I, WILLIAM L. CHURCH, a citizen of the United States,and a resident of Boston, in the county of Suffolk and State ofMassachusetts, have invented a new and useful Improvement in ReinforcedConcrete Construction, of which the following is a specification.

The present invention relates to reinforced-concrete construction, andits object is to provide a method of making a practicable, eflicient andeconomical reinforcedconcrete roof.

One form of roof made in accordance with mg method is illustrated in thedrawings w ich accompany and form a part of this specification, althoughit will be understood that various modifications may be made in detailsof construction of the particular roof shown without departing from theinvention defined in the appended claims.

In the drawings :-Figure 1 is a perspective view of my improvedreinforced-concrete roof; Fi 2 is a transverse section thereof; and Eig. 3 is a perspective view of a detail of constructions In theparticular drawings selected for more fully disclosing my invention, 1represents a supporting beam constituting a part of the wall of abuilding herein shown as formed of concrete reinforced by the rods 2. Atsuitable intervals along the top of the beam are placed oppositelydisposed saddles or gaggers 3 preferably of concrete, arranged to havetheir holes 4, shown in the present instance as three in number, inalinement. The saddles comprise, as shown, a Hat base ortion, preferablyequal in length to the t ickness of the beam on which it rests, and twoupwardly-extending diverging arms. Reinforcing members 4',

herein shown as round rods but which may have any suitable section, arepassed throng the holes 4 of each 1) in Fig. 2, and the reinforcingmember 5,

which may consist of a sheet of wire-mesh,

expanded metal or the like, is bent into appropriate shape and supported.in the sa les. In the particular construction illustrated in thedrawings, the reinforcing air of saddles as shown member-5 is shown aswire-mesh bent sinuousllyg and the lowermost parts thereof-rest in t esaddles and on the rods 4 between the saddles. When the reinforcingmember, bent into any suitable shape, has been placed in position,concrete, cement or the like is applied to both sides thereof,preferably by forcibly projecting the same by means of a cement gun. Iprefer to first coat the under side of the member to form the concreteor cement coating 6, which is about equal in thickness to that of thearms of the saddle, and afterward the upper side. As shown at 6 the rods4. are embedded in the finished structure and the roof is slightlythicker at this point than elsewhere. After the coating operation hasbeen completed, manually, 'or otherwise, the saddles, if of concrete andsaid coating form a homogeneous structure, and the rods 4' and member 5are embedded therein, resulting in a roof .of great strength anddurability.

While in the drawings I have shown the alternate ridges and guttersparallel to the slope of the roof, they may be arranged parallel to theridge-pole, and eaves, or at any other angle.

if desired the saddles may be omitted, and this1 reinforcing member 5supported by th r0 s. c

It will be obvious that the reinforcing member may be stamped orotherwise formed in various shapes, thereby giving the roof whencompleted, the appearance of ornamental, overlapping tiling.

I claim 1. The method of forming roofs consisting in placing spacedpairs of saddles on supports, restilig the gutter portions of a sinuousforaminous metallic sheet on said saddles, and applying coatings ofcement to both sides of said sheet.

2. The method of forming roofs conslsting in placing spaced pairs ofsaddles on supports, connecting each pair of saddles by reinforcingbars, resting the gutter or-. tions of a sinuous foraminous metall c seet on said saddles, and applying coatings of.

cement to both sides of said sheet and causing one of said coatings tocover said bars.

In testimony whereof, I have hereunto subscribed my name this 29th dayof Aug.
